this car has but one bank, the cam sensor is under the intake manifiold on the drivers side.
Testimonial: "thanks, now I know where to start looking. Is it a fairly easy item to replace?"
SOURCE: code reads P0340 Camshaft position Sensor circuit
That makes the computor think the timing is off. Replace the sensor and see if that does it. You will then have to have the code cleared (erased) or the light will come back on/stay on.
